The bad news is its Powdery Mildew Season, the good news is there is a good organic treatment for it called Safer Garden Fungicide.. Safer helps to prevent it from spreading. Powdery Mildew is a fungus that is spread by wind, water and by us working amongst the plants. It is mostly on the tops of the leaves and is white and powdery. You will find it most years on squash, cucumbers, lilacs, roses and more.
The best thing you can do in future years is to anticipate mildew season early and start spring Safer ahead of time. The sulfur in the product changes the ph of the leaf and prevents mildew from growing.
